Dual Flow Septic Vent

ABSTRACT

A dual flow septic vent is provided for receiving wastewater directed from a septic tank through a flow channel. The dual flow septic vent provides air intake and exhaust ventilation at the transition zone of an anaerobic environment to an aerobic environment. The dual flow septic vent includes an activated carbon filter access cover and a dosing chamber. A flow channel is provide that permits inspections of effluent flow and delivers dosed flows of root control and soil remediation components directly to a targeted site.

FIELD OF THE INVENTION

The present invention relates to septic vents for allowing air intakeand exhaust ventilation into and delivering root control, soilremediation, or other chemical agents to an onsite wastewater managementsystem.

BACKGROUND OF THE INVEN TION

Septic vents have been used for years on residential and commercialonsite wastewater systems in an effort to exhaust sewer gases exitingfrom a vertical outlet such as a vent pipe. Usually made of PVC or othernon-corrosive material, conventional septic vents commonly come in twovariations, one that extends a vent stack above grade and the other,some variation of an ornamental style vent that extends above grade. Oneof the principle draw backs to conventional septic vents is that theirdesigns do not take into account the need to easily monitor and gainaccess directly to the drain field. Conventional septic vents mayexhaust serer gases, but they do nothing to facilitate dosed amounts ofroot control or soil remediation components.

Root control is a serious problem especially in the case of onsitewastewater systems that are located near trees. Indeed, the problem isso pronounced that in order to curtail root intrusion, onsite systemowners have opted for complete tree removal. In some cases of rootintrusion, a complete wastewater system is abandoned and a new system isinstalled. These approaches to solving the root control problem are veryexpensive.

Therefore, there is and continues to be a need for a dual flow septicvent that not only dissipates serer gases from onsite wastewatersystems, but acts to control root intrusion and allows for correctmonitoring of effluent flows.

SUMMARY OF THE INVENTION

The present invention comprises a dual flow septic vent for receivingwastewater directed from a septic tank through a flow channel andallowing air intake and exhaust ventilation into and delivering rootcontrol, soil remediation, or other chemical agents to an onsitewastewater management system. The dual flow septic vent includes asurrounding sidewall structure that accepts the activated carbon filteraccess cover. A flow channel is provided that facilitates correctmonitoring of effluent flows and delivers dose flows of root control andsoil remediation components to a targeted site.

Further, the present invention entails a method of monitoring andmanaging onsite wastewater systems to ensure that the system is workingproperly as designed. The method entails directing wastewater from aseptic tank through a flow channel. Air intake and exhaust ventilationare allowed through an at grade access cover. Root control and soilremediation components are received by the dosing chamber below the flowchannel. Effluent that flows through the flow channel mixes with theaccumulated components in the dosing chamber and is dispersed accordingto flow to the final treatment area in the wastewater system.

Other objects and advantages of the present invention will becomeapparent and obvious from a study of the following description and theaccompanying drawings, which are merely illustrative of such invention.

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

With further reference to the drawings, the dual flow septic vent of thepresent invention are shown therein and indicated generally by thenumeral 10. As will be appreciated from subsequent portions of thisdisclosure, septic vent 10 is designed to be located or positioned atthe transition zone 25 following an anaerobic environment 15 such as aseptic tank 18 or a pressure manifold 18 and preceding an aerobicenvironment 35 such as a distribution device 20 that disperses effluentflow to a final treatment area. Activated carbon filter access cover 30is designed to be placed at grade level 60 and septic vent 10 extendsinto the soil media 50. Flow channel 14 is aligned with an approvedconnection 12 such that effluent flow is directed through the flowchannel 14 and across the dosing chamber 23 for final dispersion to thedistribution device 20.

Septic vent 10 includes a surrounding sidewall structure 21. Extendingbetween the sidewall structure 21 is a free access 16 to the septic vent10. Free access 16 allows for inspections of effluent flow and directplacement of root control and soil remediation components to the dosingchamber 23. Flow channel port 34 allows for air intake, exhaustventilation, and cross flow through the dosing chamber 23. The lowerflow channel port 34A indicates proper effluent flow levels. rootcontrol or soil remediation components are contained within the dosingchamber 23 and are slowly released according to effluent flow, it iscontemplated that the septic vent 10 would be made watertight andconstructed of plastic. Activated carbon filter access cover 30 would bemade of plastic and provided with a protective coating to resist UVlight. Activated carbon filter access cover 30 facilitates air intakeand exhaust ventilation via air holes 44 that are received in a recessedtrack. Activated carbon filter 55 would be configured in the activatedcarbon filter cell 41. bottom breather plate 30A terminates theactivated carbon filter access cover 30 and holds the activated carbonfilter 55 in place. Safety screws 45 secure the activated carbon filteraccess cover 30 to the sidewall structure 21.

Further, the septic vent 10 would include a fine granular material suchas sand. The granular material would be disposed beneath the bottom andwould extend upwardly within the surrounding sidewall structure 21. Byplacing the granular material around the septic vent 10, settling willbe reduced and the surrounding sidewall structure 21 can be locateduniformly over the septic vent 10.

Mixing and dosing occurs at the lower flow channel port 34A. In the caseof the design shown in FIGS. 2-3, the flow channel 14 intersects thedosing chamber 23 and as effluent travels across this intersection,products are dispersed for root control or soil remediation. Suspendedsolids or grease in effluent flows will accumulate settled solids in thedosing chamber 23 that upon inspection will indicate necessary systemmaintenance that could prevent further system damage.

In the case of septic systems that use an effluent filter or screen,exhaust ventilation is limited after the effluent exits the septic tank18. The strategic placement of the septic vent 10 in the transition zone25 reduces hydrogen sulfide (H2S) concentrations that promote corrosionand failure of system components. Air travel is not restricted at themost needed area of the aerobic environment 35.

The principle advantages of the dual flow septic vent 10 of the presentinvention are that it allows for increased air flow that will reduce theconcentration of H2S and help preserve concrete components, ease to gainaccess for inspection or product application, increased air flowdirectly at the beginning of the drain field where it is most important,ability to precisely monitor wastewater flow levels, and products can bedose delivered directly to a targeted site. dual flow refers to air flowand dose flow.
